Kollmorgen B-606-AA-99-TR
Product Classification: Frameless Brushless DC Torque Motor
Product Overview:
The B-606-AA-99-TR is a frameless torque motor from the B-Series, designed for direct-drive applications where the motor is integrated into the customer’s mechanical structure. The “TR” suffix denotes a through-hole (hollow shaft) configuration for cable routing or shaft passage.

Structural Features:
- Frameless design: No housing, no shaft — motor consists of stator and rotor only
- Through-hole rotor for shaft passage or cable routing
- Stator lamination: High-grade silicon steel, skewed slots for cogging reduction
- Rotor: Samarium Cobalt (SmCo) or Neodymium Iron Boron (NdFeB) permanent magnets
Applicable Industries:
- Direct-drive rotary tables
- Gimbal systems
- Antenna positioning
- Semiconductor wafer handling
- Medical imaging (CT/MRI gantries)
Installation Requirements:
- Stator must be press-fit or bonded into customer housing
- Rotor must be precisely balanced and aligned
- Bearing selection is customer responsibility (angular contact or cross-roller recommended)
- Thermal interface material required between stator and housing
Usage Notes:
- Do not operate without proper housing — frameless motors require external mechanical support
- Resolver signal conditioning required (Kollmorgen R-Series resolver interface recommended)
- Demagnetization risk above 150°C rotor temperature
